Named as an acronym for Amps, Volts and Ohms, AVO is best known for its iconic AVOmeter multimeter. AVO merged with Megger in the 1960s when both firms relocated from London to the Dover, England manufacturing site. AVO lives on as our training business, operating from Megger sites around the world. Click here for more information

Biddle

James Biddle was an importer of Megger insulation testers and later started manufacturing high voltage test instruments. Based in the beautiful National Park of Valley Forge, Pennsylvania, the high voltage tradition continues as Megger’s lead site for cable fault location equipment and transformer test equipment.

Megger

Manufacturing insulation testers is where Megger started, and the Megger brand name is so well known today that some maintenance professionals incorrectly use it as a verb when they refer to doing an insulation test. The Dover, England site manufactures hand-held test equipment as well as larger insulation testers, oil test equipment and low resistance ohmmeters.

Multi-Amp

Based in Dallas, Texas, the former Multi-Amp facility concentrates on relay test and circuit breaker test equipment for the world’s power industries. Started in the 1960s, Multi-Amp later merged with Biddle and then Megger to form the nucleus of today’s company.

Pax

Seeing an opportunity to create a transformer test business based around sweep frequency response analysis, engineers at Programma left to create a new business called Pax Diagnostics. Megger saw an opportunity to share the Pax innovations with more customers through Megger’s distribution network, acquired the company in 2008 and rebranded the products to Megger. Research and engineering for the product range continues at Danderyd, Sweden.

PowerDB

There was a demand for software to provide data management for acceptance and maintenance testing jobs, which was filled by PowerDB. Located at College Station, Texas – famous for its engineering school – software engineers created a database tool specifically for customers with asset management problems. Since its acquisition by Megger, it operates as a software division and continues to develop and support PowerDB. Click here for more information.

Programma

Proudly Swedish, Programma Electric AB was founded in 1976 and quickly became a world renowned supplier of test equipment and high voltage circuit breakers stationery batteries as well as portable high current applications. Headquartered in Danderyd, Sweden, the company was acquired by Megger in 2005. The business has grown in revenues and staff since that time.

SebaKMT

With its two advanced engineering and manufacturing sites in Germany (Baunach and Radeburg), SebaKMT was originally established over 60 years ago, and is the most recent member of Megger. It is the world’s leading developer and manufacturer of measurement equipment for diagnosing the condition of networks and locating faults. Market sectors include power supply networks as well as communication and pipe networks. Electrical test equipment will gradually be rebranded to Megger over the next few years, but you can continue to expect the same reliable and innovative products, whatever it is called.

STATES

Since 1911, test technicians and engineers have depended on States terminal blocks and test switches to provide easy access to wiring on panel boards and switchboards, eliminate wiring reconnection errors and saving operator time. The States business is co-located at our Dallas site. Click here for more information
